Although I asked the installer if he could do a bypass and he said (and I quote) "No sir, bypassing that safety feature is illegal. We cannot do that for you...."

 

Which probably means: " I just covered my and my shops ass, give me $20 and I will do it." :P

 

yeah, im sure that was the correct over the phone response. When Im there face to face ill see if something can be done. If a bypass is found by then, obviously. :D

Any luck guys?

 

I'm installing my z2 tomorrow and had a few questions.

I noticed someone talking about needing to install it correctly and drive it around about 50 miles to calibrate it before attempting to bypass it.

Do I really need to do this, or what that just his opinion?

 

Thanks for the help!

I know people measured the voltage on the pins back behind the Z2 and said that 3 were 0V and one was 5V. But no one mentioned if the 5V one was the same point as on the Z1 bypass. Is it in the bottom right?

 

Any luck guys?

that 50 mile calibrate thing was....

 

If you just ground the parking brake wire, it will be bypassed like you want it to be... for about 50 miles, then the bypass will stop working. So you can do something totally wrong and for the first 50 miles while it's still calibrating, it will seem correct. The 50 mile thing was more of a "wait before you claim success if the unit is brand new, because even an incorrect method will look correct for 50 miles or so". I don't think that it will not work for 50 miles and then start working.

It's too hard to use the unit without the bypass, really takes away the functionality and I agree, movies are stupid to have on while driving but choosing a POI or entering an address isn't that hard. I'm obviously waiting to hear the results when the upgrade comes out for exisitng Z1's. I'm wondering if the circuitry (wiring) is different on the Z2's and the upgraded Z1's will be OK??? Time will tell but I'm sure going to wait until I hear success from an upgrade. Maybe that's where T had the success already, on the upgrade since he seems to have an in.

it is not in the same location as the z1 i believe it is up and to the left of that pin

If that's true then that is the pin we need to ground. Some one else please confirm this. Find the pin that has 5V and try grounding that pin, even if it is different from the Z1 location.

Well I tried grounding each of the other 3 pins with a reset in between each try today still no luck. Please remember I am no expert I could have done something wrong.

Parking brake wire too?

yes

I'm sure someone has tried this already, but its a start. My outcome after only grounding the parkingbreak wire...

 

Everything is unlocked...But...

Everytime you turn on the unit, you get the warning telling you the parking break wire is incorrectly connected.

 

If you dont mind pushing and extra OK at start up, this seems to have worked for me so far.

C'mon bro, at least read the thread you're posting in. This was posted already:

z2 bypass seems to be the same. I did a z2 yesterday and it works the same as z1 but still gives parking brake message but does not lock out nav or dvd

 

 

Check the 3d calibration status. If the unit is new and hasn't been driven for more then 30-50 miles, then this could be a false sense of success. It will work for a while till the 3d calibration status turns to 3d hybrid. Then you will still get that message and it will lock you out when you start to move.

Posted Mar 26, 2007 · 02:06 UTC#62

Yes i did read. And if you notice, he said after the 3rd calibration status turns to 3d hybrid.

 

Mine is at 3d hybrid, however it is still working.

so no, this is not a double post

does it still work over 15 mph

Posted Mar 28, 2007 · 13:54 UTC#65

Z1/2 calculates speed based on the speed sense wire. Also, I'd assume the VSS wire also allows the Z1/2 to calculate mileage traveled.

 

Sooo, why not connect the speed sense to ground temporarily until a better solution is found? Do this while doing the ground-the-hidden-pin bypass.

 

This should alleviate the lock-out people experience when traveling over 15mph or after 30 miles.

Posted Mar 28, 2007 · 14:47 UTC#66

No it wont....it detects motion via internal gyros...and bases speed on the GPS along with the Speed Sense wire..

Because if the Z2 is anything like the Z2, there are 3 things it will listen to to know if you are moving or not.

 

1. The GPS antenna

2. The VSS wire

3. The internal accelerometer (Gyros)

 

You can unplug or ground #1 and #2, but you can't unplug #3. Without all 3 disconnected the Z1 can still figure out it's moving.

We never hooked the VSS wire up cuz we couldn't find it. Probably why the display shows me about 50 yards further back than i really am. I hadn't tested it while moving, and you are right, it stopped working at 10 miles per hour for me.

 

Sorry guys... I spoke too soon.

 

I'm probably just going to hook up a switch for the parking break. That way I don't have to actually apply the parking break but I can still use features when stopped at lights or signs. This will probably get rid of the error message too, just as long as I dont start driving with the switch on.

 

I'm starting to think this bypass is not possible, as you said, the internal gyros know if you are moving, and software programing probably tells it "if the parking break is on, but movement is senced, lockout the device". (as grounding the parkingbreak just tells it that the pbreak is on)

 

Someone may have to hack the software before this becomes possible.

 

Another question. Are we supposed to get the warning screen about the Nav every time we boot up? That seems dumb when I have accepted whatever agreement it was stating. I shouldnt have to accept it every time i drive the truck.

Yeah you pretty much do. I'm guessing that the "logic" behind this is that although you've accepted the agreement, the next person driving your car might not have.

You probably would have thought the same thing on an N2 or a Z1 when you first got it, but they both had easy bypasses. Just give it some time, its only been a week, previous models took much longer

If you reset the unit and then never have the parking brake switch flipped when you start moving, then yes, that will take care of the error message. But if that error message ever pops up you need to reset your unit to get rid of it.

Remember this is not trying to find a hack to trick the system in to getting around the lockouts. This is trying to find the back door that the pioneer engineers put into this unit ON PURPOSE in order to leave everything unlocked all the time.

 

The fact that the early bypasses on the z1 worked by flashing the lights, this was no accident. It was put in purposely to watch for an event (headlights flashing) and then to unlock itself.

 

We just need to find this backdoor. Every pioneer avic had one, they change it on occasion but we need to find it.

Yes you are going to get that. And yes it sounds dumb, but it's a CYA thing that Pioneer is doing because everyone out there these days is sue-happy. If we (as a whole society) would take responsibility for our own actions and actually try to work for what we get instead of trying to get rich from an accident or whatever.... this stuff will not only not go away, it's going to get worse.

Ok, I don't remember if anyone said they tried flashing the lights on the Z2, and I don't have time to read the whole thread again. It is worth a shot, and there has to be a bypass. Just a matter of time to find it. Hopefully I will have my Z2 by the weekend and I can help as well.

I'll give it a shot. What steps are involved? I never had a Z1, so I never looked this information up. Also, my pbreak sence wire is currently still grounded. Hope that doesn't keep me from testing the flashing.

I just received my z2 and will be installing it after work!...

i will post pics and any bypasses i will try.

Posted Mar 28, 2007 · 19:56 UTC#75

I have a shop in south florida called sunguard......have already installed 4 z2's.....the old bypass for the z1 does not work....TRUST ME IT DOESNT WORK
